Micrel, Inc. MIC2199 MIC2199300kHz 4mm Г— 4mm Synchronous Buck Converter General Description Features The MIC2199 is a high-power 300kHz synchronous buckDC-to-DC controller housed in a small 4mmвЂ‰Г—вЂ‰4mm MLFв„ў12-pin package. The MIC2199 operates from a wide 4.5Vto 32V input and can be programmed for output voltagesfrom 0.8V to 6V. The wide input voltage capability makesthe MIC2199 an ideal solution for point-of-load DC-to-DCconversion in 5V, 12V, 24V, and 28V systems.The 300kHz switching frequency allows the use of a smallinductor and small output capacitors. The current mode PWMcontrol along with the external COMP pin allows for ease ofstability compensation and fast transient response across awide range of applications.An all N-Channel synchronous architecture and powerfuloutput drivers allow up to 20A of output current capability.For smaller external components, refer to the 500kHzMIC2198.The MIC2199 is available in a 12-pin 4mmвЂ‰Г—вЂ‰4mm MLFв„ўpackage with a junction temperature range from вЂ“40В°C to125В°C. 4.5V to 32V input range4mmвЂ‰Г—вЂ‰4mm MLFв„ў package300kHz PWM operation95% efficiency …
